What you'll learn

Businesses and organizations must manage and analyze vast amounts of data efficiently in today's data-driven world. Slow query responses and inefficient data handling can significantly impact your business. In this course, Advanced Functions in SQL Server: Performance and Practicality, you'll learn to optimize database performance through advanced SQL Server functions. First, you'll learn how to write user-defined functions for advanced data manipulation, including scalar, table-valued, multi-statement functions, as well as writing clean, efficient, and reusable code. Next, you’ll discover techniques for optimizing these functions' performance, particularly in large databases. Finally, you’ll learn how to differentiate between deterministic and nondeterministic functions, identify and avoid common pitfalls in function usage, and apply functions for efficient data manipulation and analysis in real-world scenarios. When you’re finished with this course, you’ll have the skills and knowledge of advanced SQL Server functions needed to design, implement, and optimize complex functions, improving data retrieval speeds, report generation, and overall database efficiency.
